If this is a 23l batch, this is going to be strong - serve in wine glasses. I would expect this to be a big flavour Cherry wine, with a slight hint of ale. I doubt the hops will get a look in.

You are brewing a 5ish% beer and then then adding a huge amount of fermentable sugar with the cherries.

Also bear in mind the cherry skins may float (rise up on the co2), so these will need punching down 2x daily. So your want a wide neck Fv or better a bucket and forget the airlock unless you are prepared for a cherry missile crisis.

Was that what you had in mind?

Thats was my first impression - should have asked is this a known recipe or a creation?

Hi mashy, my wish was to create a beer which was light like lager but with the flavour of Dr Pepper soda. The soft drink is big on cherry and almond flavour and very sweet. Hence the lactose for unfermntable sweetness and saaz to blance a little, in essence a fruit beer with almonds and back sweetness. One of my sons drinks shit like kopperburg cider so I want to bring him down the true path of beer drinking slowly but surely. I use a coarse muslin for the cherry weighed down with a few stainless steel ball bearings , and there is plenty of krausen room in a fermenatsaurus, should be shooting at about 5.4 % depending on the cherries.

Then you have two products you can blend in a 100ml glass and taste various proportions. That keeps the maths easy (70/30 etc). You can back sweeten at the same time. With a 10% solution of nonfermentable sweetener. Ditto vanilla.

Setup a ten glasses 90/10, 80/20 through to 10/90 and then have a tasting party.

This will get you the drink you want and its a good fun party drinking game.
